hi I have a openCV based Objective C project for video which works correctly by itself, where I am trying to calculate intensity gradient using Sobel operator using the stack overflow example ([login to view URL]) but it is giving me error. I need to calculate average gradient and resulting direction of image from phone. Can you please fix the error.

STACK OVERFLOW CODE

Mat img = imread("[login to view URL]", IMREAD_GRAYSCALE);

// compute the image derivatives for both the x and y direction

Mat dx, dy;

Sobel(img, dx, CV_32F, 1, 0);

Sobel(img, dy, CV_32F, 0, 1);

Scalar average_dx = mean(dx);

Scalar average_dy = mean(dy);

double average_gradient = atan2(-average_dy[0], average_dx[0]);

cout
